United States Patent TRANSPORTING DEVICES FOR FILLED BOBBINS Johann Geiger, Wuppertal, Elberfeld, Germany, assignor to Vereinigte Glanzstolr Fabriken A.G., Wuppertal, Elberfeld, Germany, a joint-stock company This invention relates to textile machinery in which yarn is collected on bobbins, and more-especially to the full bobbins and to a new way of transporting them in unwrapped condition from the receptacle in which they are disposed when taken from the spinning machine, doubler or spooler to the weaver or other consumer.

Hitherto the full bobbins were collected on mandrel frames, after wrapping of each bobbin in aluminum foliae, cellophane or wax paper, which were then put in pasteboard boxes and shipped in crates. All this required much time and labor and the yarn on the bobbin was often soiled When being handled or otherwise damaged by the wrapping material. One has tried to simplify the transport of the bobbins by placing them in vertical position in the crates, being centered therein by means of sockets, pivots or the like provided in the cover or bottom of the crate. However here again the outer yarn layers were likely to be damaged and entangled.

According to the present invention the full bobbins, on being disengaged from the spinning or other machine, are placed directly on racks running on rolls which engage rails provided in a transfer truck. When a rack is filled up with bobbins, it is transferred by the truck to a dustproof shipping container provided with a door in its side wall which can be closed tightly by means of rubber packings to prevent the outer air from entering. In this shipping container rails are provided on a level with the rails on the truck so the racks can glide from the truck into the container. filled with racks, it is closed and can be shipped. On arrival the racks with the bobbins stored thereon are withdrawn and carried by similar transfer trucks to the weaving or other devices.

The yarn, by being transported in this manner, is protected throughout the transport against soiling by contact with the hands. All the operations hitherto gone through can be dispensed with. Owing to the bobbins being supported on the racks on horizontal mandrels, an entanglement caused by concussions during the transport is avoided. The closing of the doors of the shipping container results in maintaining the same climatic conditions within the shipping container as existed in the room where the yarn was produced. Even if the climatic conditions should change temporarily and if condensation of occluded and evaporated moisture should occur, the absolute content of moisture would be preserved and the normal climatic conditions required for the working up of the yarn would be restored as soon as the shipping container is allowed to rest some hours in the room at which it has arrived before being opened.

In the drawing affixed to this specification and forming part thereof, equipment for transporting or shipping filled bobbins in the manner described above, is illustrated diagrammatically by way of example.

In the drawings:

Fig. 1 is a diagrammatic representation of the con- When the container is 2,963,182 Patented Dec. 1960 ICC 2 secutive phases of the shipping process, showing the several devices employed accordingto this invention.

Fig. 2 is a perspective view of a transfer truck sup porting a rack on which the bobbins withdrawn from the yarn making machine are stored, and of a shipping container to which said rack is being transferred.

Fig. 3 is an end view of the rack supporting transfer truck, and

Fig. 4 is a detail, drawn to a large scale, showing the rack support on'the truck of Fig. 3.

Referring to the drawings and first to Fig. '1, the filled bobbins 1 are transferred to and mounted onthe rack 2 'slidably supported by rails 5 at the bottom of the transfer truck 3. Each rack 2 is tared and the weight of the filled rack is ascertained bymeans of the balance, which also has rails 5' and 6 for the racks. The racks are now returned to the truck which is-then placed in front of the shipping container '7 and the racks are transferred to the rails 5" and and 6" provided in the three compartments of this container. The doors 10 are closed and the three racks stored therein are ready for transport to the consumer.

Of course it is possible to temporarily locate the racks storing the filled bobbins in an intermediate station and in that case it is recommended to store the racks in storage containers similar to the shipping container 7. These intermediate containers may be larger, but need not have the high degree of stability. On the other hand large rooms provided with dustproof doors and with supporting rails corresponding to rails 5 and 6 may be provided for the racks. Such an arrangement offers the advantage, over the present way of storing the bobbins in their Wrappings, that an easy control of the number and condition of the bobbins is rendered possible.

Fig. 2 which is drawn to a larger scale, shows a ship ping container 7 subdivided into three compartments which are separated by means of plywood or plastic partitions. In each compartment of the shipping container two filled racks 2 can be accommodated. The shipping container 7 has tightly fitting doors 10. Rubber packings are provided in the joints between the boards of the container and in the door frames. The top rails 6" and the entire roof of the shipping container 7 should not be. made of metal such as iron and should not contain any metallic parts, since at low temperatures water would condense on the metal.

Fig. 3 is an end view of the transfer truck 3. The centre support mounting the mandrels 12 is provided in the form of tubes 11 to which the mandrels are welded. The bobbins, either filled or empty, are mounted on these mandrels which are preferably provided with rubber rings 13 and 14 at both ends (Fig. 4). As a rule the bobbins will not slide off horizontally mounted mandrels 12, but it is preferred to dispose these mandrels at a slight inclination. Within the shipping container 7 the partitions 9 prevent the bobbins from leaving the mandrels, even if the container is exposed to vigorous shocks and concussions, because between the free ends of the mandrels and the walls and partitions of the shipping container, only a gap of less than 1" is left.

The rack 2 is supported by two rollers 15 (Fig. 4), which can roll in, and are supported by, the rails. The position of the rails 5, 5, 5" in the various units is so arranged that the racks 2 can be transferred without any intermediate guiding means to the rails of any of the devices here shown and described, by means of foldable guiding members (not shown).

I wish it to be understood that I do not desire to be limited to the details above described and shown in the drawings for obvious modifications will occur to a person skilled in the art.

I claim:

1. A transportation and interim storage system for filled yarn bobbins, comprising in combination, a rack including a series of mutually spaced, substantially hori- -zontally extending mandrels adapted to engage and firmly support said bobbins, a transfer truck for moving said rack and a dustproof shipping container, said shipping container being provided with a pluralityof compartments and with rails in each compartment for engaging said bobbin supporting racks, said compartments having walls which are disposed in such close proximity to the free ends of the mandrels on said racks as to prevent any substantial displacement of the bobbins in the course of shipment of said containers, rail engaging means on said rack and rails on said transfer truck to facilitate transfer of said bobbins with said rack tosaid container whereby the bobbins remain on the same rack from their removal from the machine on which they are made, through shipment and to their final placement.

1 2 A transportation and interim storage system as claimed in claim 1 wherein said rail engaging means on said rack consists of rollers and adapted to be moved in and out along the rails of said truck with the rails of 4 said truck and the rails of said container being in horizontal alignment to permit transfer of said rack to said container.
